She should use Mean. That is when you add together all of the numbers, then divide by the number of numbers. Her average grade is 80.75, or rounded it is 81.

I need help on this ASAP pls 20 points
Semenov [28]

Answer:

1070cm2

Step-by-step explanation:

the cereal box represents a cuboid and it is closed hence a closed cuboid.

SA- Surface area

L- Length = 15

W- Width =4

H- Height =25

In a closed cuboid, there are going to be 6 faces( 3 pairs).

To find SA, we have to take the area of all faces and sum them up.

You can do this by carrying out the area of all faces and summing them up or you can use the formula:

SA of a closed cuboid=2(L x W) + 2(W x H)  + 2(L x H)

= 2(15 x 4) + 2(4 x 25) + 2(15 x 25)

= 2(60) + 2(100) + 2(375)

=120 + 200 + 750

=<u>1070cm2</u>
